Exercise 24 Page 845

Use the formula for the volume of a pyramid.

42 000 000 cubic feet

Practice makes perfect

The Pyramid Arena in Memphis, Tennessee, is approximately h=350 feet tall, and its square base is 600 feet wide.

Since the base is a square that is 600 feet wide, its area is B=600^2=360 000 square feet. Now we will find the volume of the Pyramid Arena using the formula for the volume of a pyramid.

V=1/3Bh

Substitute values and evaluate

SubstituteII

B= 360 000, h= 350

V=1/3( 360 000)( 350)

Multiply

V=1/3* 126 000 000

MoveRightFacToNumOne

1/b* a = a/b

V=126 000 000/3
